Last updated: 2023-09-07

The Air Quality Index (AQI) is a crucial tool for understanding outdoor air quality and its effects on health. This guide breaks down the six AQI categories, their implications, and how you can monitor air quality effectively. For deeper insights, platforms like Clime offer functionalities that complement AQI information with weather data and environmental alerts.

Summary

• AQI Overview: The AQI categorizes air quality levels from good to hazardous.
• Health Implications: Each category ranges from minimal to high health concerns based on air quality data.
• Color Coding: The AQI uses a color scheme to easily convey air quality levels.
• Clime Features: Using Clime allows you to receive weather updates and environmental alerts alongside AQI data.

What are the six AQI categories and their health implications?

The AQI is a standardized measure that informs the public about air quality. **There are six categories:

1. Good (0-50)**: Air quality is satisfactory; pollution poses little or no risk.
2. Moderate (51-100)**: Acceptable air quality, although there may be a concern for a small number of people who are unusually sensitive to air pollution.
3. Unhealthy for Sensitive Groups (101-150): Members of sensitive groups (like those with respiratory conditions) may experience health effects. The general public is not likely to be affected.
4. Unhealthy (151-200): Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects.
5. Very Unhealthy (201-300): Health alert: everyone may experience more serious health effects.
6. Hazardous (301-500): Health warnings of emergency conditions. The entire population is more likely to be affected.
